It is not necessarily the case.
No.
No.
A mixed number is a combination of an integer and a proper fraction.
No, it can be greater than 4.
No, and it is not always less than 4, either.

No.
A mixed number is a number with both a whole number and a fraction.
No.
No, it is not true.
The statement is false.
No.
A mixed number is a combination of an integer and a proper fraction.
The mixed number consists of a whole number and a fraction. Multiply the denominator of the fraction portion by the whole number and to this product add the numerator of the fraction portion. This value is the numerator of the new improper fraction. The denominator of the new improper fraction is the same as the denominator of the original fraction portion of the mixed number.
The statement is false.
No, it can be greater than 4.
The question is ambiguous. Do you want to know how to multiply a fraction by a whole number, as well as by a mixed number? Or are you asking how to multiply a whole number by a mixed number and express the product as a fraction? Or what?
